On A Flag Pole or Staff
Except when flown at half-staff, always fly the US flag at the top of the flag pole. The US flag should be above or to the viewers left of non-national flags. In a grouping of national flags, the US flag should be to the viewers left; the US flag should not be above the other national flags. On stage, the US flag is displayed on the speaker's right (the audience's left).
When hung over a street or on a wall without a flag pole or staff, hang the US flag vertically with the union to the north or east. Over a sidewalk, the union should be farthest from the building.
The US flag may be displayed vertically or horizontally. The union (stars) should be at the top to the observer's left.
